# confdb\_fd\_get(3)

Dispatches callbacks from the CONFDB service

## NAME

confdb\_fd\_get - Dispatches callbacks from the CONFDB service

## SYNOPSIS

**#include \<corosync/confdb.h\>**

**int confdb\_fd\_get(confdb\_handle\_t** *handle***, int \****fd***);**

## DESCRIPTION

The **confdb\_fd\_get** function is used to retrieve the file descriptor that may be used with the poll system call to determine when **[confdb\_dispatch(3)](/confdb_dispatch/3.md)** won't block.  The *handle* argument may not be used directly with **poll** because it is not the file descriptor, but instead an internal identifier used by the CONFDB library.

## RETURN VALUE

This call returns the CONFDB\_OK value if successful, otherwise an error is returned.

## ERRORS

The errors are undocumented.
